metodo non definito `validate_presence_of 'per RSpec :: ExampleGroups :: User :: Validations

Question

Sto provando a passare le specifiche del modello per la convalida, ma non sono in grado di farle passare. Ho messo tutte le regole di convalida nel mio file di modello così

app/modello/user.rb

class User < ActiveRecord::Base 
    has_many :friendships 
    has_many :friends, :through => :friendships 
    has_many :plans 
    has_many :memberships, class_name: "PlanMemebership" 
    has_many :notes 
    has_many :replies, class_name: "NoteReply" 
    has_many :upvotes, class_name: "NoteUpvote" 

    validates :first_name, presence: true 
    validates :last_name, presence: true 
    validates :email, presence: true 
    validates :facebook_user_id, presence: true, uniqueness: true 
    validates :facebook_user_token, presence: true, uniqueness: true 
    validates :token, presence: true, uniqueness: true 
    validates :birthday, presence: true 
    validates :gender, presence: true 

    def name 
    first_name + " " + last_name 
    end 

end 

spec/modelli/user_spec.rb

require 'rails_helper' 

describe User, :type => :model do 

    context "valid Factory" do 
    it "has a valid factory" do 
     expect(FactoryGirl.build(:user)).to be_valid 
    end 
    end 

    context "validations" do 
    it { should validate_presence_of :first_name } 
    it { should validate_presence_of :last_name } 
    it { should validate_presence_of :email } 
    it { should validate_presence_of :birthday } 
    it { should validate_presence_of :gender } 
    it { should validate_presence_of :facebook_user_id } 
    it { should validate_presence_of :facebook_user_token } 

    context "uniqueness" do 
     before { create(:user) } 
     it { should validate_uniqueness_of :facebook_user_id } 
     it { should validate_uniqueness_of :facebook_user_token } 
     it { should validate_uniqueness_of :token } 
    end 
    end 
end 

spec/factories/users.rb

FactoryGirl.define do 
    sequence(:facebook_id) { |n| "#{n}1004453333331" } 
    sequence(:facebook_user_token) { |n| "#{n}CAA" + ("X" * 216) } 

    factory :user do 
    first_name "Ralph" 
    last_name "Robot" 
    email "ralph@thoughtbot.com" 
    facebook_user_id { generate(:facebook_id) } 
    facebook_user_token 

    birthday { Date.current } 
    gender "Male" 

    token { Token.new.generate } 
    end 

end 

Test uscita

Token 
    #generate 
    returns a 20-byte token 

User 
    valid Factory 
    has a valid factory

Answer 1

penso che è necessario aggiungere quanto segue al spec_helper.rb

require 'shoulda/matchers' 

vostre specifiche mancano metodi shoulda di matcher.

Ecco la fonte. Puoi controllare. La gente si lamenta di cose simili. https://github.com/thoughtbot/shoulda-matchers/issues/384

Answer 2

Aggiungere rspec-rails e shoulda-matchers nel Gemfile:

group :development, :test do 
    gem 'rspec-rails', '~> 3.4', '>= 3.4.2' 
    gem 'shoulda-matchers', '~> 3.1', '>= 3.1.1' 
end 

Impostare il spec/rails_helper.rb utilizzare rspec-rails e shoulda-matchers:

require 'rspec/rails' 
require 'shoulda/matchers' 

E aggiungere nel vostro spec/spec_helper.rb:

Shoulda::Matchers.configure do |config| 
    config.integrate do |with| 
    with.test_framework :rspec 
    with.library :rails 
    end 
end
